new species
(Figs. 1A–B, 4–7)
Diagnosis.
Distinguished from other congeners by the somewhat (posteriorly) ovoid body, grayish brown basic coloration, small eyes, short, blunt-tipped median projection on frons, and noticeable skull-like markings on the hemelytron (Fig. 1B, circled image).
Description.
Body generally grayish brown, somewhat ovoid; dorsal surface mat or shagreened, with sparsely distributed, long, silky, erect setae and short, reclining, woolly setae. Head whitish, with irregular sanguineous stripes laterally; frons with a short, thumb-like, blunt-tipped median projection; eye small; vertex wide. Antenna grayish brown, partly tinged with red; segment I coffee brown. Labium shiny dark brown, long, extending beyond apex of metacoxa, reaching abdominal sternum VI or VII. Pronotum with white basal margin; collar area with sanguineous spots; mesoscutum with four tooth-like, dark markings; scutellum arched mesially, with pale apex; pleura dark brown, rather shiny; episternum tinged with red; ostiolar peritreme creamy yellow. Hemelytron irregularly speckled, with a set of four dark, skull-like markings on clavus and corium (Fig. 1A–B); cuneus dark brown, rather strongly deflected at cuneal fracture; membrane dark smoky brown. Coxae and legs dark brown, except for pale metacoxa, all tibiae and tarsi brown. Abdomen unicolorously dark brown.
